在 vb.net 中获取文件路径

Question

I'm using this code to get a list of current proccess.

For Each Proc As Process In ProcessList
Dim ProcessList As List(Of Process) = Process.GetProcesses.ToList
 Dim Name As String = Proc.ProcessName
 Dim Path As String = Proc.MainModule.FileName
Dim Icon As System.Drawing.Image = System.Drawing.Icon.ExtractAssociatedIcon(Path).ToBitmap
next

but I get an error on Dim Path As String = Proc.MainModule.FileName) which I think is because I'm using 64bit OS.

Thanks in advance

First of all you have ProcessList declared in your loop. I assume that was a paste error.

The problem is that you can't access all the processes like that. You will need to add a try catch.

Dim ProcessList As List(Of Process) = Process.GetProcesses.ToList
For Each Proc As Process In ProcessList
    Dim Name As String = Proc.ProcessName
    Dim v = Environment.Is64BitProcess
    Try
        Dim Path As String = Proc.MainModule.FileName
        Dim Icon As System.Drawing.Image = System.Drawing.Icon.ExtractAssociatedIcon(Path).ToBitmap
    Catch ex As Exception
        Debug.WriteLine("Can't Access File Name: " + ex.Message + ", Process Name: " + Name)
    End Try
Next
